Abstract:

The k-means problem is a classical combinatorial optimization problem which has lots of applications in many fields such as machine learn-ing, data mining, etc. We consider a variant of k-means problem in the spherical space, that is, spherical k-means problem with penalties. In the problem, it is allowable that some nodes in the spherical space can not be clustered by paying some penalty costs. Based on local search scheme, we propose a (4(11 + 4 root 7) + epsilon)-approximation algorithm using singe-swap oper-ation, where E is a positive constant.
